In a 2006 interview, Federline revealed that he and Spears had collaborated on "a few tracks" together in addition to "Crazy". He stated, "I think people need to get to know me a little bit more, and that way when we do something, people will respect it that much more."[1]
These songs are likely produced by Disco D or Christopher "Notes" Olsen.
